Objective To discuss the causes of sustained quit ear after radical mastoidectomy, and the longterm results of radical remastoidectomy including tamping of the radical mastoid cavity, reconstruction of the external auditory canal wall, and tympanoplasty. Methods 14 patients (14 ears) who were undergone the radical mastoidectomy with postoperative sustained quit ear or repeated infection were given radical remastoidectomy. Meanwhile, the radical mastoid cavity was tamped with pedicle soft tissue flap and/or temporal muscle flap, and the external auditory canal and superior tympanum were reconstructed with mastoid cortical bone. Tympanoplasty was applied to those with indications. Results After followed up for one to five years postoperatively, all 14 ears remained dry, and the shape of external auditory canal kept normal or slightly expanded. Conclusion With advantages as followings: ① maintenance of a dry ear due to tamping of the radical mastoid cavity and normal or slightly expanded external auditory canal, ② improvement of hearing owing to concomitant tympanoplasty, the radical remastoidectomy including tamping of the radical mastoid cavity, reconstruction of the external auditory canal wall and tympanoplasty is worthy to be popularized.
